A Potential Understory Flora For Oak Savanna In Iowa, Karl T. Delong, Craig Hooper

Journal of the Iowa Academy of Science: JIAS

Oak savanna occurred in Iowa until the time of settlement and then was degraded rapidly. There were no scientific studies of savanna prior to, or after, settlement, and now no high-quality examples exist within the state. To identify those vascular plants adapted to live in the understory of savanna we examined regional and local flora for species that occurred in both prairie and broken woodland, and for species that occurred m both openings and forest. We then compiled a detailed description of the ecological range of habitats for each of these species. We identified 252 species (39 graminoids, 183 forbs, …

The Natural History Of Aconitum Noveboracense Gray (Northern Monkshood), A Federally Threatened Species, Margaret A. Kuchenreuther

Journal of the Iowa Academy of Science: JIAS

Aconitum noveboracense Gray (Ranunculaceae), commonly known as northern monkshood, is a federally threatened herbaceous perennial that occurs in disjunct populations in Iowa, Wisconsin, Ohio and New York. It appears to be a glacial relict, existing today only in unique areas with cool, moist microenvironments, such as algific talus slopes. Field studies reveal that A. noveboracense has a complex life history. Perennation of individual plants occurs through the annual production of daughter tubers. Vegetative reproduction is commonly observed, and can occur by means of aerial and subterranean bulbils, as well as by development of adventitious root buds. Populations also reproduce sexually …

Geochemistry Of Buried Midcontinent Rift Volcanic Rocks In Iowa: Data From Well Samples, Karl E. Seifert, Raymond R. Anderson

Journal of the Iowa Academy of Science: JIAS

We analyzed welt cores and cuttings from deep wells into Precambrian igneous rocks from five separate pacts of the buried Midcontinent Rife System in Iowa for major and trace elements. A total of 21 samples, 9 cores and 12 cuttings, were analyzed for trace elements by instrumental neutron activation analysis (INAA) and 11 of these, 9 cores and 2 cuttings, were analyzed for major elements by inductively coupled plasma (ICP) analysis.

Pathogenicity Of Septoria Aquilina Isolated From Black Hills Bracken, A. Gabel, C. Salazar

Journal of the Iowa Academy of Science: JIAS

Septoria aquilina, a pathogenic fungus isolated from Pteridium aquilinum growing in the Black Hills was studied from 1991-1995. S. aquilina sprayed at 8,000 conidia/ml on transplanted fronds followed by high humidity caused severe necrosis seven days after inoculation and disease severity increased until fronds died. Severe necrosis also developed from inoculations at 4,000 and 2,000 conidia/ml. Less severe symptoms developed from inoculations at 1,000 conidia/ml. Inoculations at 4,000 conidia/ml not followed by high humidity caused less necrosis than inoculations at the same concentration with high humidity. Inoculations at 4,000, 2,000, and 1,000 conidia/ml on fronds grown from spores caused similar …

An Annotated Checklist Of The Spiders Of Northwestern Iowa And The Loess Hills Of Western Iowa, Barbara J. Abraham

Journal of the Iowa Academy of Science: JIAS

Spiders were collected by the author from various habitats in 16 counties of northwestern Iowa and the loess hills of western Iowa during the summers of 1985 and 1990-1992. Additional donated specimens from the same region in 1981and1989 were identified by the author. Twenty-three families, 92 genera and 184 species have been identified.

Bald Eagles Wintering Along The Des Moines River, Iowa, Neil Sabine

Journal of the Iowa Academy of Science: JIAS

Distribution, habitat use, and foraging behavior of Bald Eagles (Haliaeetus leucocephalus) wintering in southeast Iowa were studied in January - March 1990 and November 1990 - March 1991. Eagles were seen from November through March with the highest numbers in January and February. Adults had shorter winter residence times than immatures and they appeared to be less active during the day. Eagles concentrated their foraging efforts along certain river segments where they fed exclusively on fish. Timber harvesting along the river reduced eagle use and is considered to be the most serious threat to sustaining eagle use of the area. …

Current Status Of The Plains Pocket Mouse, Perognathus Flavescens, In Iowa, Gregory M. Wilson, John B. Bowles, Justin W. Van Zee

Journal of the Iowa Academy of Science: JIAS

Published and unpublished accounts of the plains pocket mouse (Perognathus flavescens) were utilized to document the existence of extant populations and to summarize and report additional data about the biology of this state endangered Iowa species. Populations of P. flavescens exist in western (Harrison, Monona, and Plymouth counties) and extreme eastern (adjacent portions of Louisa and Muscatine counties) Iowa, the latter of which represents the eastern-most record for the species in North America. In addition, we document a new locality for P. flavescens from the interior of the state (Benton County). All known populations of P. flavescens in Iowa occur …

Book Review - The Unnatural Nature Of Science: Why Science Does Not Make (Common) Sense, David Lopatto

Journal of the Iowa Academy of Science: JIAS

A distinguished psychologist once wrote that if you wished to understand the history of scientific thought you need a psychologist at your elbow. Lewis Wolpert, Professor of Biology at University College in London, has taken that sentiment further. It seems that if you wish to understand the difference between scientific and nonscientific thinking you should delve deeply into the literature of cognitive psychology. For natural thinking, "ordinary, day-to-day common sense will never give an understanding about the nature of science." Instead, the trained scientist engages in unnatural (i.e., counterintuitive) thinking about a word that defies ordinary experience. In order to …

A Relationship Between River Modification And Species Richness Of Freshwater Turtles In Iowa, Terry J. Vandewalle, James L. Christiansen

Journal of the Iowa Academy of Science: JIAS

Comparisons were made of turtle populations in Red Rock Reservoir and the major rivers of the Mississippi River and Missouri River damage systems in Iowa. Of the inland rivers of the Mississippi drainage examined in this study, the Des Moines River had the least amount of remaining turtle habitat. Number of turtle species ranged from five in the Des Moines River to 11 in the Mississippi River, but only three species were found in Red Rock Reservoir. In the Missouri drainage, number of turtle species ranged from three in both the Little Sioux and Nishnabotna rivers to five in the …

Life History And Status Classifications Of Birds Breeding In Iowa, Louis B. Best, Kathryn E. Freemark, Barbara S. Steiner, Timothy M. Bergin

Journal of the Iowa Academy of Science: JIAS

Life history and status classifications were compiled for 145 bird species that breed in Iowa. Species were classified by food type and substrate, nest substrate, susceptibility to cowbird parasitism, migratory status, predominant habitat use and habitat-use specialization, body mass (an index of home range/territory size), area sensitivity, population trend and vulnerability, and beneficial/harmful aspects in relation to agriculture. Such information may be used to make interspecific comparisons, evaluate interrelationships among life history and status characteristics, and provide insights into the interpretation of previous research. This synthesis also can aid those responsible for making conservation and management decisions about Iowa's avifauna.

Is Library Automation Feasible For All Elementary Schools?, Tiffany Bayless

Graduate Research Papers

Library automation has been adopted by many library media centers, but is it appropriate for all libraries? The justification for automation of four library media centers will be based on the literature reviewed, current operations of these centers, and personal experiences and observations in working with these library media centers. There have been many concerns about whether library automation is feasible for these library media centers, and that is the reason for the focus of this study. Library automation should not be something that is implemented just because "everyone else is doing it".
